Changeset 271

Author:

Message:
  • Bugfix: The ISR_SWITCH index should be NB_PROCS_MAX + local_pid. This is because the first NB_PROCS_MAX indexes on the XICU in each cluster are used for the WAKEUP software interrupts.
  • Relocating the memcpy and memset functions into the giet_libs/stdlib.* files.
  • Modification of the sort application to used 8 threads instead of
    1. Modifying the mapping files to distribute the 8 threads on the available processors. (Ex. When using 4 processors, each one executes 2 threads)
